Ionic compounds are not molecules. Examples include sodium chloride (NaCl), magnesium sulfate (MgSO4), calcium carbonate (CaCO3), and Iron oxide (FeO, Fe2O3, or Fe3O4).
Not all compounds are molecules. NaCl (salt) is an example of an ionic compound. Some molecules, such as O2, are comprised of only one kind of atom and are therefore not compounds.
All but H2, O2, F2, Br2, I2, Cl2, and N2. Those are diatomic elements, and when they are bonded together they are just referred to as the name of the element. (O2 is just called Oxygen instead of...
